Rising damp Mould & condensation Wet patch / leak Not sure yet

Your details are safe — we never share them. ★★★★★

Damp walls have one of three causes: rising damp from the ground (tide marks on lower walls), penetrating damp through the wall (patches that worsen with rain), or condensation (surface mould in cold spots). Correct diagnosis is essential because each needs a different treatment — and treating the wrong one wastes money.

What is wall damp?

Walls are where damp shows first, and where misdiagnosis costs homeowners most. A wall replastered without fixing the underlying moisture source will be damp again within months. Equally, fitting a chemical DPC to a wall that actually suffers condensation fixes nothing.

Our surveyors profile the moisture in your walls — measuring at multiple heights and depths, checking external defects and ventilation — to pinpoint the cause with certainty. Then we recommend one treatment plan, in writing, with a fixed price.

Signs of wall damp to look out for

  • Damp patches, dark staining or discolouration on walls
  • Tide marks on ground-floor walls (rising damp)
  • Patches that spread after rain (penetrating damp)
  • Surface mould in corners and behind furniture (condensation)
  • Cold, clammy walls and musty smells
  • Crumbling plaster, peeling paper, salt deposits

Spotting one or more of these? Don't wait — damp problems only get more expensive with time. Book a free survey and we'll tell you exactly what's going on.

How we treat damp walls

Depending on the diagnosis, treatment may include damp-proof course injection and salt-resistant replastering, external repairs and breathable masonry protection for penetrating damp, insulated dry-lining for cold solid walls, or ventilation systems that stop condensation at source.

Every wall we treat is left structurally sound, dry and ready to decorate — and the treatment is backed by our written guarantee.

Wall Damp FAQs

Wall Damp — your questions answered

Why does my wall feel damp to the touch?

Cold solid walls often feel damp because airborne moisture condenses on them — but genuinely wet walls indicate rising or penetrating damp. Our moisture profiling distinguishes the two in one visit, free of charge.

Can damp walls make my family ill?

Yes — damp walls breed mould, and NHS guidance links mould spores to respiratory infections, allergies and asthma, with children and older people most at risk. Treating damp is a health investment, not just cosmetic.

Do you replaster after treating the damp?

Yes. Damp-contaminated plaster usually has to be replaced with a salt-resistant system, and we handle the full job — strip, treat, re-render, skim — leaving you ready to decorate.

How soon will my walls dry out?

Expect roughly one month of drying per 25mm of wall thickness after the source is fixed. We advise on heating, ventilation and breathable finishes to speed it up safely.
